Is this moving inland now or is it just my eyes? To me, it looks to be over land already (although I may be wrong).

ATCF has the center at around 14.7N, which is a bit offshore. Though most of the convection is moving onshore, now yes.

TROPICAL STORM BORIS DISCUSSION NUMBER 5
NWS NATIONAL HURRICANE CENTER MIAMI FL EP022014
200 PM PDT TUE JUN 03 2014
Although the satellite presentation of the tropical cyclone has
degraded during the past few hours, a couple of ASCAT passes
at 1524 and 1618 UTC detected winds of 34 to 37 kt over the
northeastern portion of the circulation. Based on the ASCAT
data, the system was upgraded to a tropical storm on the 1800 UTC
Intermediate Public Advisory. The initial intensity remains 35 kt,
however, additional strengthening is not anticipated since a large
portion of the circulation is already interacting with land. Boris
should steadily weaken after landfall, and the low-level
circulation is expected to dissipate over the mountains of southern
Mexico in a couple of days.
The initial motion estimate remains northward at about 4 kt. Boris
should continue moving slowly northward around the eastern side of
a mid- to upper-level trough over Mexico. The model guidance is in
somewhat better agreement on taking the system inland over southern
Mexico within the next 24 to 48 hours. The updated NHC track
forecast is similar to the previous advisory and is near the TVCE
model consensus.
The primary threat from Boris continues to be very heavy rainfall
and the resultant flooding over southeastern Mexico during the next
couple of days. Rainfall totals could approach 30 inches (750 mm)
in the states of Oaxaca and Chiapas, which will likely cause
life-threatening flash floods and mud slides in areas of mountainous
terrain.

TROPICAL STORM BORIS DISCUSSION NUMBER 6
NWS NATIONAL HURRICANE CENTER MIAMI FL EP022014
800 PM PDT TUE JUN 03 2014
Boris has a rather disorganized appearance on satellite imagery,
and consists of a couple of clusters of very deep convection near
the coastline. Although it is questionable as to whether the
cyclone is still a tropical storm, the current intensity is
maintained at 35 kt as a precaution since the convection is still
strong. This is also in agreement with a Dvorak Current Intensity
estimate from TAFB. The cyclone will weaken after crossing the
coastline, presumably in a few hours, and the surface circulation is
expected to dissipate over the mountainous terrain of southeastern
Mexico in 36 hours - if not sooner.
Although the center has been very difficult to locate on
geostationary imagery, an AMSR2 microwave image from earlier today
provided a fairly good center fix. This enabled some adjustments
to the working best track of Boris, and extrapolation into this
evening suggests that the storm has moved closer to the coast than
earlier estimated. The cyclone should continue to move slowly
northward on the western side of a mid-level ridge that extends
westward from an anticyclone centered over the western Caribbean
Sea. The official forecast track is a little faster than the
previous one, and moves the center of Boris over southeastern
Mexico over the next day or so. This is close to the latest
dynamical model consensus.
As the weakening tropical cyclone moves inland, it is likely to
continue to produce very heavy rainfall. These rains will cause
life-threatening flash flooding and mud slides over the mountainous
regions of the Mexican states of Oaxaca and Chiapas over the next
couple of days.

TROPICAL DEPRESSION BORIS DISCUSSION NUMBER 7
NWS NATIONAL HURRICANE CENTER MIAMI FL EP022014
200 AM PDT WED JUN 04 2014
The center or area of minimum pressure associated with Boris
apparently crossed the coast of Chiapas, Mexico near the city of
Tonala around 06 UTC. Since that time, satellite images and surface
observations indicate that the alleged center is rapidly losing
definition, and it is taking the appearance of an elongated
north-south trough of low pressure. I would not be surprised if
there are a couple of centers of circulation along such trough. I
was tempted to declare Boris a remnant low, but I would rather wait
for early morning visible images and keep the system as a tropical
depression at this time.
The depression appears to be moving northward or 360 degrees at 5
knots. Most of the guidance suggests that Boris or its remnants will
continue on this slow track over the high terrain of southeastern
Mexico and dissipate later today.
Boris or its remnants, in combination with a trough of low pressure
in the Bay of Campeche will continue to produce very heavy rainfall.
These rains will cause life-threatening flash flooding and mud
slides over the mountainous regions of the Mexican states of Oaxaca
and Chiapas over the next couple of days.

Re: EPAC: BORIS - Tropical Depression
TROPICAL DEPRESSION BORIS DISCUSSION NUMBER 8
NWS NATIONAL HURRICANE CENTER MIAMI FL EP022014
800 AM PDT WED JUN 04 2014
Visible satellite images and surface observations suggest that Boris
has not moved much this morning with a large increase of convection
near and south of the apparent center. Since surface observations
are inconclusive on whether a well-defined center still exists, it
is best to keep advisories going for one more cycle. It is likely
that Boris will dissipate later today while it moves slowly
northward and becomes a part of a large trough of low pressure
extending from across the Isthmus of Tehuantepec northward into the
Bay of Campeche.
Boris or its remnants, in combination with a trough of low pressure
over the Bay of Campeche, will continue to produce very heavy
rainfall. These rains will cause life-threatening flash floods and
mud slides over the mountainous regions of the Mexican states of
Oaxaca, Chiapas, Veracruz and Tabasco over the next couple of days.

Re: EPAC: BORIS - Remnants
Is over.
REMNANTS OF BORIS DISCUSSION NUMBER 9
NWS NATIONAL HURRICANE CENTER MIAMI FL EP022014
200 PM PDT WED JUN 04 2014
Visible satellite images and surface observations show that
Boris has degenerated into a trough of low pressure. Thus, this is
the last advisory on this system. The remnants of Boris should move
slowly northward and become part of a large trough of low pressure
extending from across the Isthmus of Tehuantepec northward into the
Bay of Campeche.
The remnants of this system, in combination with the Bay of Campeche
trough, will continue to produce very heavy rainfall during the
next couple of days. These rains will likely cause life-threatening
flash floods and mudslides across the Mexican states of Oaxaca,
Chiapas, Veracruz and Tabasco, especially over mountainous regions.
